Q1: If you were to see deficiencies in your no till or soil grow typically you would add a dose of what you believe the plant is lacking. Using PPM to regulate that dose is a standard practice.

Q2: We are having a grower’s challenge for anything grown with SK lighting and that is what the hashtag is for. To bring it to people’s attention and get more entries.

Yes, you must have Spectrum King LED and show which one you use
